A strapping apparatus for strapping articles with a strapping band having a base plate provided for arranging on an article, a tensioning device with which a band tension can be applied to the strapping band, and a sealing device for permanently connecting two band layers to each other.

An assembly for producing sealed packaging units (14) from a sheet packaging material, comprises: an advancement device (21) for advancing the sheet packaging material along an advancement direction (F), a longitudinal sealing device for sealing opposite borders of the sheet packaging material along a longitudinal sealing band arranged parallelly to the advancement direction (F), thereby forming a continuous tube (15), a transverse sealing device (29) for sealing the continuous tube (15) transversely to the advancement direction (F), so as to define a sealed packaging unit (14). The transverse sealing device (29) comprises a sealing element (30) and an abutment element (31) that are intended to mutually cooperate during sealing while being located on opposite sides of the continuous tube (15). The sealing element (30) is so configured as to act on a side (27) of the continuous tube (15) on which the longitudinal sealing band is provided.

The invention relates to a method for producing strapping. A strapping band (4) is first guided about at least one packaging piece, tightened, and equipped with a closure at band ends (4a, 4b) to be connected in a closure unit (1). Furthermore, at least one sensor (7) connected to a control unit (8) is provided in the closure unit (1). One or more closure parameters are detected by means of the control unit (8) using the sensor (7), and the closure unit (1) is correspondingly actuated. According to the invention, the sensor (7) is designed as a load cell (7) which is let into a compression ram (6a, 6b) of the closure unit (1).

A sealing machine is provided for sealing a sealing material by heating a fin of the sealing material wrapped around a product. The sealing machine comprises, in a transport direction of the sealing material, a pair of tracking rollers for tensioning the sealing material and a pair of heating rollers for sealing the sealing material by applying heat to the fin when the fin is moved between the pair of heating rollers. Furthermore, the pair of tracking rollers and the pair of heating rollers are configured to be driven independently.

A welding device includes a pair of pressure rollers for pressurizing a web and a strip member, a feed device configured to intermittently or continuously feed the web and the strip member through the pair of pressure rollers, and the laser device configured to irradiate the web or the strip member with a laser beam at a position upstream of the pair of pressure rollers. The welding device may include a movement device configured to move the pair of pressure rollers upstream with respect to the web and the strip member during pause or stop of feed. Alternatively, the feed device may pause or stop the web and the strip member after retracting the web and the strip member by a certain length.

An automatic splicing apparatus and methods thereof are provided herein for splicing together two ends of a sheet of tire material on a tire building drum. The apparatus comprises a frame, a splicer foot assembly, and a splicer roller assembly. The frame is configured to support the apparatus relative to the drum. The splicer foot assembly and the splicer roller assembly are independently longitudinally translatable relative to the frame. The splicer foot assembly includes a splicer foot having forward lower preparation rollers and rearward lower splicer rollers, and upper preparation rollers configured to operate in coordination with the forward lower preparation rollers to pull the two ends of the sheet of tire material together over the splicer foot. The splicer roller assembly includes upper splicer rollers configured to act in coordination with the rearward lower splicer rollers to splice the two ends together.

A fusion welding device, comprising a fusion welding work motor, a fusion welding work moving assembly, and a fusion welding work fixed assembly, the fusion welding work motor being connected to the fusion welding work moving assembly by means of a transmission mechanism. The fusion welding device is provided with a central connection component that is able to rotate, and the central connection component is provided with a first input position, a second input position, and a locking structure connection position. The present fusion welding device is able to implement automatic band pressing and fusion welding work by means of relatively simple structural cooperation, and by means of differently transmitted front and back connections and changes in engagement, and is able to automatically lift the fusion welding work moving assembly without requiring a handle or related operations.

A method of constructing an inflatable fluidic actuator that includes generating a tube configuration with one or more shapes of fluid-impermeable membrane material, the tube configuration having a first tube end and a second tube end and an internal tube face and an external tube face. The method also includes coupling a first and second interface to the tube configuration at the first and second tube ends by respectively coupling each interface to the tube configuration at a respective tube end by generating at least one of: a first circumferential bond between the fluid-impermeable membrane material and one or more sidewalls of the interface; and an external face bond between fluid-impermeable membrane material at the tube end onto an external face of the interface.

A fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers is provided. The fin sealer is configured to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller.

A thermoplastic product includes a fabric-based reinforcing sheet and a polymerized thermoplastic material. The fabric-based reinforcing sheet is wound about a mandrel to form a plurality of layers having a cross-sectional shape that corresponds to the mandrel. The fabric-based reinforcing sheet includes a plurality of fiber bundles, which may have a bidirectional orientation or configuration. A polymerized thermoplastic material is disposed within each layer of the fabric-based reinforcing sheet. The polymerized thermoplastic material bonds each layer of the fabric-based reinforcing sheet to an adjacent layer.
